How New Jersey's limits on 'forever chemicals' in tap water brought levels down

Levels of toxic "forever chemicals" in New Jersey's public water systems dropped by as much as 55% after the state moved to limit the contaminants in drinking water, according to a Rutgers Health researcher who has analyzed 19 years of monitoring data from throughout the state. Their findings in Environment International represent one of the first formal evaluations of whether state-level regulations on per- and polyfluoroalkyl substances (PFAS) effectively reduce contamination.
